This invention relates to separable fasteners of that kind in which series of complementary interlockin elements are arranged along the opposed e ges of a gap or opening in a garment, shoe, receptacle,or other article made of suchllexible material as textile fabricz leather,` or rubber and relates more particularly to sliders or such fasteners.

Y For certain purposes fasteners of the above type as ordinaril made are not wholly satisfactory, since wit the usual construction it is necessary permanently to close the gap or opening in the garment at one end. Thus when employed for closing the fronts of sweaters, coats, and the like, it is necessary for the wearer to draw the garment over his head when putting it on or taking it off, whereas the older forms of fastener, such as hooks, snaps, or buttons., are not open to this objection. h

I am aware that certain attempts have heretofore been made to remedy this deficiency in fasteners of the present t pe by making the slider in two parts capa le of separation so that the gap can be opened intermediate its ends, but so far as is known to me, all such previous expedients have been objectionable either from the standpoint of the cost of production of the fastener, from the cumbersome and unsi htly `appearance of the device, or from the diiculty of assembling and separating their parts.

In accordance with the present invention I have followed a similar course in that I divide my slider into two separable sections, but in so doing have avoided complexity o construction, or abnormal size or appearance, and in accordance with a preferred method herein disclosed I provide a' slider which may be formed from sheet material by simple stamping and bending operations; which is light in Weight; of relatively small dimensions; stiff and durable; which may be made at low cost whose parts are preferably united by a snap socket connection permitting them readily to be separated or assembled without moving them relatively in a longitudinal direction, and without manipulating latches or equivalent means, and by such separation tpermiting the ga to be opened at' an esired oint; an which works smoot y and freely in opening and closin the gap. A

Referring to the drawings, the numeral l designates a coat or sweater provided at the edges of its front opening with series 2 and 3 of fastener elements of any well known type. These fastener elements, for example, maybe of the kind disclosed in the patent to Prentice No. 1,658,392, February 17, 1928, wherein the several elements of each series are independent, or, on the other hand, the fastener-elements may be of the type shown in the patent to Prentice No. 1,677,408, dated July 17, 1928 wherein the elements of a series constitute the turns of a helical coil spring, yit bein understood that whatever ci c type of astener element be employed, t e guide elements of the slider hereinafter more fully described will be of appropriate sha to` accommodate the fastener elements. Y Iii'ferably a stop 4 is secured at the u per and lower ends respectively of each o the series 2 and 3 of fastener elements. Such sto is preferably of sheet'material and may we be of the kind shown in Figs. 7 and 8 of the atent to Prentice No. 1,658,392 above' reerred to. However, it is contemplated that other forms of sto may be employed and the specific form o stop forms no essential part of the present invention.'-

In Fig. 1 the front opening in the garment is shown as closed, the series 2 and 3 of fastener elements being interengaged and the actuating slider 5 being disposed at the top of the opening. The extreme bottom of the opening below the ends of the fastener elements is referabl provided with a fla 6 having a huttonho e for engagement wit a button 7. Obviously a hook and eye, sna or anyother equivalent means may be su stituted for the button and buttonhole. While this auxiliary fastener is not necessary, it is preferable to employ it or its equivalent in order that flexing of the garment at its lower part may not' result in separation of the series and 3 of interengaging fastener elements.

Referring more particularly to Figs. 3 to 7, the improved shder 5 comprises the lefthand section 11 and the right-hand section 12, it being understood that I refer to these parts as left-hand and right-hand sections merely for convenience in description and that I do not necessarily limit myself to this particular relative arrangement since the parts may be reversed in vplosition, if desired, without departing from t e spirit of the in. vention. The right-hand section includes a back'member 8 of resilient and preferably thin sheet material having forwardly turned flanges 9l and 10 (Fig. 8)` at its edges. The right-hand section 12, as shown more par-v ticularly in Figs. 5, 7 and 8, comprises a fastener guide having a rearwall 13, an inner wall 14z and a front wall 15, therear and front walls being provided with inwardly directed anges 16 and 17 (Fig. 8)7 defining between them a slot leading into the guide -channel 18. This guide channel is adapted to receive the right-hand series 3 of fastener elements and the walls of this channel may be shaped appropriately to receive the particular type of fastener element with which the slider is to'be employed.

In assembling the right-hand guide with the back member, it is disposed against the bent-up front face of the back member with its lian 16 engaging the flange 10. When thus s1- tioned, the inner wall 14 of the rightand geuide cooperates with the resilient back memr 8 and its flange 9 to form a resilient sna socket for the reception of the left-han guide elementas hereafter more fully described. The rear wall 13 of the right-hand guide referably is furnished with lugs 19 (Fig. which are bent over against the rear side of the back member 8, thus securing the guide permanently to the back member. Obviously, other fastening means may be used if desired. I

The front wall 15 of the right-hand 'de is furnished with a forwardly directedillug M provided with an elongate slot S for the rece tion of a tongue 29 carried by the lefthan section, 11, as hereinafter described. The front member 15 of the right-hand guide is also4 provided with a tongue member 20 which extends first upwardly, and then downwardly in parallel relation to the front wall 15, and whose lower end is eng by the extending downwardly from the Ywall 15.

end portion of a second tongue 21 The tongues 20 and 21V form a loop adapted to receive a pull ldevice 22 having an opening through which the loop p, the pull device being movable Vfrom the lower art of the loop to the upper art to facilitate movement of the slider in either direction.

' The left-hand section 11 comprises a guide having a rear wall 23 (Fig. 8), a front wall 24, andan inner wall 25, the outeredges of the walls 23 and 24 being bent to form inwardl directed flanges 26 and 27 respectivel d ing between them a slot leading into t e ide channel 28 for the lefthand series of astener elements 2. The innerl walls 14 and 25 of the right-hand and left-hand guides extend onl ,part way down the length of the slider so that'the guide'channels 18 and 28 merge at the lower end of the slider as is usual in sliders of this type. If desired, the lower edges of the walls14 and'25 may be beveled so as collectively to form a wedge,

shaped divider plate to facilitate separation of the slider elements of the o posed series.

The front wall 24 of the leftf furnished with the forwardly divergent ton e 29 adapted to pass through the slot S a ove descnbed and to revent relative longitudinal movement oft e sections, thus assisting in holding the left-hand section 11 in proper assembled relation with the righthand section. Y

. .The back member 8 extends across the entire width of the slider, being of such dimensions that wihen the hlt-hand section 11 is pressed into e orwa open sna socket defined by the outer surfyaee of wall114, the

nt fa of the back member s, and the right-hand face of resilient I 9,) the flange' 9-frictiona11y section 11, tendin to prevent the latter from s rmging forwar and away from the back.V efore snapping the section 11 into its socket,

'the tongue 29 is'frst inserted in the slot S, and

the engagement of these parts eiectivelyprevents relative longitudinal movement of the 'slider sections during use. When it is desired to separate the parts of the fastener, it

. the gap open, as shown 1n Fi 2 In constructing the slider a ove described, I preferably prepare blanks, such as shown in Figs. 9, 10 and 11, by suitably 'stamping or punching them from sheet material by means of diesV or otherwise. Thus, as shown in Fig. 9, the blank 11-is suitably shaped for makin the left-hand section 11 of the slider. This blank, as shown, comprises parts 26, 27 and 29"which when bent along the dotted lines are adapted to form the side flanges and the tongue of the guide mem- .ber 11.

In Fig. 10 I have shown the blank 8* which iadapted' to form the back of the completed s 1 er.

In Fig. 11 I have indicated a blank 12* appropriate for forming the right-hand guide member of section 12. This blank comprises parts 13, 14", 15, 16, 17 19, 20 and 21* which when bent along the dotted lines and at certain other obvious points are adapted respectively to constitute the parts 13, 14,' 15, 16, 17, 19 and 2O of the guide. This blank has the punched out slot S, and the incision B defining the lug M. Having provided the blank 12, its various parts, with the exception of the tabs 19, are bent to proper position, the pull device `22 being threaded over the tongue 20l before the latter is engaged with the tongue 21. The back member 8'L is then arranged against the outer Wall of the member 13* 'and the tabs 19'* are turned over to hold the back member in place.

The completed sections 11 and 12 are now mounted on the left-hand and right-hand series respectively of fastener elements and the stops 4 are secured in position. The sections 11 and 12 are moved down to the lower end of the series of fastener elements; the section 11 is engaged with the socket in the section 12; and the slide is ready for use. The

operation of the slide has already been de# scribed.

While I have herein disclosed one desirable embodiment of the invention and have described a desirable mode of making this embodiment, I wish it to be understood that the inyention'is not limited to the specific details of construction herein disclosed or to the specific mode of making the' device, but that `variations in shape, size and relative arrange! ment of parts, and thesubstitution of equivalents ma be'made, and vthat adiiferent order of steps 1n making the device may be adopted without departing from the spirit of the invention.
